Course Introduction：Java uses the iterator() function of the Set class to traverse the elements in the collection. Set in Java is an unordered, non-repeatable collection. When traversing the Set collection, we can use the iterator() function to obtain an iterator, and then traverse the elements in the collection through the iterator. First, we need to create a Set object and add some elements to it. For example, we create a HashSet object named set and add some integer elements to it. impor
